The filing and the timing
Anthropic has filed a document with the SEC announcing its intention to list on Nasdaq under the symbol ANT. This is reported by ANSA Tecnologia, according to which the transaction would be in preparation for November. Sources familiar with the matter indicate the week of November 16 as a possible window, noting that the date may change.
It would be a debut on the Wall Street markets for a company founded in 2021, and therefore with about five years of activity, described by the source as a protagonist of the generative AI boom. The combination of its short history and the size of the transaction is the element the source describes as historic.
Size of the transaction
According to what was reported by the Wall Street Journal and taken up in the reconstruction, the IPO could raise up to $100 billion or more, with an overall valuation of the company between $1.5 trillion and $2 trillion. These are estimates, not confirmed values: the filing concerns the intention to list, while the price and final amount will depend on the offering phase.
The comparison between the two figures helps gauge the scale of the transaction: the hypothetical raise corresponds to a limited share of the expected valuation, a sign that the company's value is largely already incorporated in market expectations rather than in the cash raised through the IPO. It remains to be seen what the actual price range will be and how much of the capital will be offered.
Business models and shareholding structures
The source situates Anthropic's growth in the corporate world: companies have invested capital to seize growth opportunities and improve internal efficiency. According to the material, expansion accelerated in 2026 with the boom in Claude Code, an AI-based programming tool, and with advanced models such as Claude Fable 5 and Mythos 5.
On ownership, the material indicates that the founders are among the largest shareholders, ahead of the large investment firms. CEO Dario Amodei holds or controls 245 million shares; Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah each own more than 200 million Class A shares. Among the venture capital firms cited are Iconiq, Lightspeed Venture Partners and Menlo Ventures, which could obtain significant gains. The source recalls that Dario Amodei co-founded the company in 2021 after leaving OpenAI, now its main competitor.
What remains to be verified
The picture outlined is based on a filing and anonymous sources: the week of November 16 is not a fixed date, and the same source admits that the timing may change. No per-share price, number of shares offered, or breakdown between newly issued shares and sales by existing shareholders is indicated. These elements will determine the actual scale of the raise relative to the $100 billion estimates.
A second issue concerns the valuation: the $1.5 trillion–$2 trillion range is attributed to the Wall Street Journal and not to an official document. The offering will show whether the market shares those expectations. The source does not report comments from Anthropic, the SEC or Nasdaq, nor details on the company's risks or revenues.
